Your developer/site name I presume would be your business's name? If so, then register it as a trademark brand, which will give you (very) limited protection. Each IP address is also unique, but the only realistic protection against 'near names' is owning all of the IP near names yourself. That is, unless you have millions to spend on lawyers.
Most of your game elements will not be able to be IP protected unless you can product something both stunningly unique, and instantly recognisable in the wider marketplace; plus have protections already in place before 100 spoofs are made.
For you to ask this question, you don't understand the limitations of copyright, or of trademarks.
Here's a little thing I wrote several days ago here. The second last paragraph has relevant info on some limitations.
